Americans don't just own a lot of pets, we are WEIRDLY attached to them. Here are the results of a new survey in honor of "National Love Your Pet Day," which is today, apparently . 1. Dogs are the most popular pet in America. They're followed by cats . . . fish . . . birds . . . and then hamsters and gerbils. 2. 10% of people regularly say "I love you" to their pet. 3. 10% talk to their pet in a special voice. 5. Only 4% admit that they probably post TOO MANY pictures of their pet on social media.
